Tropical fish print dress

[kittenteethvintage]

I picked up this muumuu style dress the other day and am just so in love with the charismatic sea creatures and bright coral print. The tag inside is long disintegrated and I don't see any signature in the pattern nor on the interior selvage. Anyone recognize the print?
Also, re age - although the print reads earlier to me (50's-60's), the style and plastic zip are leading me to appx 70's. Any thoughts on age?

I'm thinking 70s, mainly just based on the look of the colors and the print in general. I don't recognize the print I'm sorry to say.

This style of fish print looks more like later 80s to me. The cartooned version of photo realism!
